GASOLENE-ENGINE.

SPECIFICATION forming part of Letters `Patent No. 653,971, dated July 17, 1900. Application iiled October 2l, 1899.*` Serial No. 734,304. (No model.)

fo @ZZ whom t may concern: A

Be it known that I, FRANK JOSEPH SPROEHNLE, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Gasolene-Engines,which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an improved construction of a gasolene-engine in which the number of part-s is reduced to a minimum and provision made for manufacturing engines of this character in a cheap and effective manner.

It also consists of a novel construction of controlling-valve and its adj uncts, said valve being operated by suitable tripping mechanism carried by the connecting-rod of the engine, whereby the admission and ignition of the commingled air and gas or gasolene are effectively regulated.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a transverse sectional view of a gasolene-engine embodying my invention, certain of the parts being shown in elevation. Fig. 2 represents a plan view of the engine seen in Fig. 1, showing especially the valve-operating mechanism. Fig. 3 represents a section on linea@` 00 Fig. 1. Fig. 4 represents a partial side elevation and partial vertical section of certain of the parts seen in Fig. 1, some of which, however, are in different positions from those seen in Fig. l. Fig. 5 represents a plan view of certain of the parts seen in Fig. 4. Fig. 6 represents a partial side elevation and partial vertical section of certain of the parts seen in Fig. 4. Fig. 7 represents a plan view of certain of the parts seen in Fig. 5, some of which, however, are in diierent positions from those seen in said Fig. 5.

Similar letters and numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, ct designates the engine, the same consisting of a cylinder b,

which is surrounded by the water-jacket c,

i said cylinder containing the piston d, which has connected thereto one'e'ndof the connecting-rod e, the other endof the latter being suitably attached to thecrank-pin f, which is mounted on the crank g of the shaft h, which latter carries the balance or fly wheel c'. The connecting-rod e is provided with a dog j, which is adapted to contact with the portion k of the tripping member l' which is pivoted upon the pin m and has the portion o carried thereby adapted to contact with the ends p of the lever q, which is fulcrumed at r, said lever being provided with the raised portion s, on which is adapted to rest the extremityt of the rod u, which isv mounted in a suitable guide or bearing o, said endif being in contact with said raised portion by reason of the spring w, one end of the latter contacting with said guide o and the other end thereof contacting with the pin or abutment no, carried by said rod, the action of the above parts being rendered positive by suitable springs. (Best seen in Fig. 3.) The rod u is provided with the offset portion y, to which is attached the inlet-valve plug e, the latter having the port 1 therethrough, said valve being movable in a suitable seat 2, contained in the casing 3, into the upper portion of which latter leads a pipe 4 for conveying the gas, gasolene, or other fluid.

5 designates a passage leading from a point below the valve c through the port 6, from which the gasolene is discharged into the interior of the cylinder b, the requisite quantity of air being admitted through the port 7.

8 designates an air and gas valve mounted on the rod 9 .and adapted to close the port 6 at proper intervals, said valve-rod carrying a head 10, against which contacts one end of the spring 11, the other end of the latter contacting with the adjacent portion 12 of the cylinder or cylinder-head through which the rod '9 passes.

13 designates an arm attached to the valve c, the lower extremity 14 of said arm being adapted to contact with the rod 9, so as to move the valve 8 to the desired extend at proper intervals, as will be explained.

The ignition of the charge of` gas or gaso- IDO ^ the extremity of the rod u, as seen in Figs.

of the electricity conveyed to the electrodes 15 and 16 by the conductors 17 and 18, respectively, the contact being closed by means of the pin or projection lf), which is attached to the piston d, it being apparent that when said piston moves to its extreme righthand position the projection 19 closes the circuit between said electrodes. When the said pin moves away from said electrodes, the contact is broken, therebycausing the electric spark, which effects the ignition of the charge which enters through the port 6. Y

The operation is as follows: When the parts are in the position seen in Fig. 1, the piston is advancing to the left, and the suction created thereby unseats the valve S, and the gasolene and air enter through the passage 5 and port 7, respectively. Itis to be understood that, the extremity 2O of one of the projections 21 on the raised portion s is in contact with land '7, and that when the rod u is in this position it has been moved to its full extent to the right, so as to bring the port 1 in the Valveplug z in alinement wit-h the passage 5 in orderY that the gasolene may iiow through said port 1, passage 5, and port 6 and enter the cylinder b, it being noted that when the valve-v plugz isin the position seen in Figs. 1 and 7 the. dogj is in contact with the portion lo of the memberZ and causes the portion o carried. by the latter to impart a partial rotation to the raised portion s, due to the forward movement of the' connecting-rod e, thereby turning said raised portion s sufficiently to bring the same into the position seen in Fig. 5, whereupon the rod 'u will be caused to slide to the left by the action of the spring fw and to abut against one of the shoulders 22 on the raised portion s, and thus cause the valveplug e' t o move into the position seen in Figs. 5 and 6, whereupon the supply of gasoleue to the cylinder b will be cut off, it beingunderstood that the piston d has not as yet completed its full movement to the left. When the several movable parts of the engine are in the positions seen in Figs. 2 and 4, the piston CZ has completed its movement to the left, due to the explosion in the cylinder b, andthe raised portion s has been turned, as hereinbefore described, so as to cause it to be in the position seen in Fig. 2, whereupon the spring w will still further advance the rod u to the left and in so doing will cause the end 14 of the arm 13 to force the rod 9 to the left, as seen in Fig. 4, against the` action of the spring 11, and thus open the port 6 to permit the escape of the waste products of the explosion. The momentum of the wheel t' causes the piston b to be moved to its full extent to the right, then to the left, and when moving in the latter direction the connection-rod e will again operate the valveplug z, as hereinbefore described, in order to again supply the cylinder b with gasolene for a subsequent explosion. It is to beV noted that when the arm 13 has been moved, as hereinbefore described, from the position seen in Fig. 1 to that seen in dotted lines iu the same figure the end 14 of said arm 13 will occupy such a position that when the port 6 is closed by the plug 8 the head 10 of therod 9 will be brought in contact withv the end 14 of the arm 13, so that when said arm 13 completes its movement to the left it will cause L thepurpose hereinbefore described. As soon as the piston commences its return stroke to the right prior toan explosion, which occurs at every fourth stroke of the piston, the valve 8 is caused to seat and the charge of air and gas is compressed until the projectionv 15 closes the contact between the electrodes,

toward the left again.

If desired, a plurality of valves. 8 may be used, one serving as an inlet-valve andthe other as an exhaust.

Having thus described my invention, what I claim as new, and desire to secure by Letters. Patent, is-
